Blue Series Pushbutton Switches

TE ALCOSWITCH's Blue series switches are well suited for designs requiring human interface via pushbutton style switches

Image of TE Connectivity's Blue Series Pushbutton SwitchesTE ALCOSWITCH's Blue series pushbutton is based on an innovative snap-action mechanism that produces an extremely fast switching moment. This high level of dynamics not only reduces arcing and bounce but it also results in a high number of duty cycles. The series comprises versions with SPDT and DPDT configurations and can be ordered with push on / push off or momentary function. The actuator cap of the push-button switch is available in many colors and sizes.

This miniature pushbutton is easily integrated into compact control/front panels. Despite its small case dimensions, the actuator gives a clear reliable feedback that confirms proper operation. At 265°C the solder heat resistance of the ALCOSWITCH Blue series pushbuttons is high enough for efficient, RoHS compliant wave soldering technology.
